Onkyo TX-84 Quartz Synthesized Tuner Amplifier 1987 Black

Nice receiver.  I go through playing through each of the inputs in the videos I linked.  Vintage 1987 stereo equipment.  Has inputs for CD, two tape decks, a record player, two video ins left and right, plus video in and out. 
You could hook a bunch of stuff up like your iPad and a dj mixer and a turntable and a synthesizer.  You could probably figure out how to use it as a guitar amp or a P.A., but I used it to play records on a turntable through its phono input and cassettes through tape 1 most of the time.  Watch the videos, all the inputs are good.
